• Universal using (bulk solids, liquids, aggressive materials, petroleum products etc.)
• Direct mounting into various containers, silos, vessels, tanks, filling inlets, reservoirs, etc.
• Sensitivity and hysteresis fluently adjustable
• Output types NPN, PNP, NAMUR
Capacitive level sensors DLS® are designed for limit sensing of the level of liquid and bulk solids in tanks, sumps, tubes or, hoppers, silos, etc. The sensors are manufactured in several modifications of sensing electrodes (rod and rope). The electrodes can be given an insulating coating, a useful feature in case of adhesive, aggressive or conductive media sensing. Rod electrodes are also available in a version with reference tube for measuring fluids in tanks made from non-conductive material.
Sensors are manufactured in the following configurations: N – for non-explosive areas, Xd – For use in flammable dust atmospheres; Xi – Explosion proof – intrinsically safe for hazardous (explosive) areas and XiM – Explosion proof – intrinsically safe for use in mines with methane or flammable dust presence danger (see technical specifications). There are high temperature performance NT, XiT, XiMT available and various types of process connection (metric and pipe thread, jointless connection Tri-clamp).
